利用實驗設計法改善陣列光纖酒精滲透不良之問題---以A公司為例

Abstract

隨著全球光纖通訊FTTX (Fiber To The X)的蓬勃發展，光纖被動元件舉足輕重，其中朝向價廉及體積小的發展趨勢，以陣列光纖元件(Fiber Array Unit，FAU)最有競爭優勢，雖然FAU的製程發展已多年但市面上產品仍無法全數通過嚴苛且漫長的環境測試要求，然成品的前期酒精滲透測試是環境測試前產品品質確認的重要指標。 本研究的個案公司為一光纖被動元件廠（稱為A公司），其FAU產品發展及出貨多年，在目前市面上也有一定的市占率。但A公司發現FAU產品隨著通道數及產品間距規格不同，其酒精滲透的良率也隨之不同，在排除多項可能造成異常的原因後，A公司認為問題可能肇因於組成材料（玻璃上蓋、光纖及玻璃基板）的清潔程度影響膠水的黏著，導致產品酒精滲透。為協助A公司釐清造成異常的原因，本研究利用實驗設計法，發現影響組成材料（玻璃上蓋、光纖及玻璃基板）清潔程度的主要原因為Plasma清潔的氣體跟生產環境濕度的控制，可有效提升FAU酒精滲透良率。

Recently according to global fiber optics grows up rapidly, and passive fiber optic components become to play an important role on market. Most importantly is Fiber Array Unit （FAU）which develops to smaller and cheaper. Although FAU has already developed many years, it’s difficult to all pass strictly environment test. And alcohol wicking test is an important index about FAU’s quality confirmation before environment test. A fiber optic passive component A company produces FAU many years, but always has unstable alcohol wicking problems in different channels and core-pitch products. A company thinks the problems come from uncleanness raw materials（Lid glass, Fibers and V-groove chip）affect adhesive bonding for alcohol wicking. This research tries to use DOE （Design of Experiment） to find out the major root cause of FAU’s alcohol wicking problems. And the conclusions find out the gas of plasma and environment’s humidity control are the key factors to improve the yield of FAU’s alcohol wicking.
